Oceanic blue carbon is a new concept recognizing how carbon can be fixed and stored in the ocean and seafloor sediments through the actions and influences of living marine organisms (e.g., fish, krill, sea turtles, and marine mammals such as whales and dugongs).Innovative infographics, developed by GRID-Arendal and partners with support from the UNEP Blue Forests Project, have helped advance discussion of oceanic blue carbon in the arenas of science, economics and policy.
